Michigan J Frogged
Whenever a certain problem or situation is happening but when you go to show someone else the problem or situation either fixes itself or stops happening. Comes from the Michigan J Frog cartoon where the singing frog will sing for the lone man but stops whenever he tells someone to check it out causing everyone to think he is crazy.
My fucking car just Michigan J Frogged me pretty bad. It was making these weird, loud sound all week long but when i went to take into the auto repair shop it stopped making that sound and it sounded just normal to the maintenance guy so i still don't know what's wrong with it.

Having an erection anytime except when its time to perform.
I swear it always gets hard but right now I'm having a Michigan J. Frog!
